Problems solved by technology

However, as polycrystalline silicon panels become bigger, the data and gate lines become longer, parasitic capacitance and resistance increase, and the display signal is delayed.

Embodiment Construction

[0027] FIG. 3 shows an exemplary circuit diagram of a method of driving a liquid crystal display according to the present invention.

[0028] In FIG. 3, parasitic capacitors Cp1, . . . Cpn are individually connected between corresponding data lines DL1, . . . DLn of a display panel and a common voltage Vcom. Alternatively, the data lines DL1 . . . DLn may include additional capacitors connected between each of the data lines DL1, . . . DLn and each corresponding gate line GL, and capacitors connected between the data lines DL1, . . . DLn and corresponding pixels P1, . . . Pn. The additional capacitors are implemented as line capacitors for a block driving method. For example, even though a data switch may be opened after a data signal is applied from a signal line Si to a data line DL, the data signal is continuously maintained by a corresponding data line capacitor. The capacitance of the data line DL may be designed at least one-hundred times as large as the capacitance of a correspo...

Abstract

A liquid crystal display panel driving circuit includes a plurality of data signal lines, a plurality of data lines, a plurality of data switches, each data switch connecting at least one data signal line to the plurality of data lines, a plurality of pixels, a plurality of pixel switches connecting a data signal transmitted on each data line to at least one of the pixels, and a plurality of capacitors, each capacitor connected to at least one of the data lines for storing a voltage corresponding to the data signal transmitted by one of the data switches and for transmitting the voltage to one of the pixels.

Description

[0001] The present invention claims the benefit of Korean Patent Application No. P2000-85390 filed in Korea on Dec. 29, 2000, which is hereby incorporated by refexence.[0002] 1. Field of the Invention[0003] The present invention relates to a liquid crystal display, and more particularly to a circuit and method of driving a liquid crystal display.[0004] 2. Discussion of the Related Art[0005] Generally, liquid crystal display (LCD) devices control light transmittance of liquid crystal cells in accordance with an electrical signal, thereby displaying an image. An active matrix LCD device includes switching devices for each liquid crystal cell, thereby sequentially displaying multiple images to generate a moving image. The active matrix LCD device uses thin film transistors (TFTs) as the switching devices. Since the LCD device has smaller dimensions than a conventional display tube, LCD devices have been widely used in personal computers, notebook computers, office automation equipment ...
